"Dizzy" is a song originally recorded by Tommy Roe, with instrumental backing from L.A. session musicians known as the Wrecking Crew, which was an international hit single in 1969.

Written by Roe and Freddy Weller, "Dizzy" was a major hit on both sides of the Atlantic, reaching number one on the U.S. Billboard Hot 100 for four weeks in March 1969, for one week on the UK Singles Chart in June 1969, and was #1 in Canada in March 1969.

"Dizzy" has eleven key changes total between a total of four keys. One key is used for the verses, while the choruses get three keys. The key used for the verses is the lowest, while the choruses start off in a higher key, quickly increases to an even higher key, then increases yet again.

It was subsequently recorded by such disparate artists as Boney M, Mike Melvoin and the Deadbeats, Wreckless Eric and Billy J. Kramer.

In 1989, it was sampled by De La Soul on a remix by Chad Jackson of their track "The Magic Number" from their album Three Feet High and Rising. In 1994 it was covered by Babe on their album 4 Babe pesme; the Babe version being entitled "Dizel".

In 2005, "Dizzy" was used in the soundtrack of The Sandlot 2.

On 14 October 1991, a cover of "Dizzy" recorded by English comedian Vic Reeves and the alternative rock band The Wonder Stuff, was released in the United Kingdom, reaching number one in the UK Singles Chart in the third week of release and staying there for two weeks. This added another key change to the eleven that already exist (from F major to G major).
